Title: What new insights does SITELLE unveil about NGC 6888 and NGC 2359?

Presenter: Marcel Sévigny

Abstract:

We will present some results from our detailed SITELLE study of NGC 6888 and NGC 2359, two Wolf-Rayet nebulae, and how those new results are improving our understanding of massive stars evolution. Among other results, we will present a detailed temperature map of some filaments in NGC 6888, numerous emission line characterizing those late stages and a very interesting first map of the [NeIII] 3869 line. Finally, velocity maps of both nebulae are particularly impressive since they provide a detailed insight into the interaction of multiple phases of stellar wind with with the interstellar medium.
